The stimulation of cerebral N2-methyl- and N22-dimethyl guanine-specific tRNA methyltransferases by methionine sulfoximine: An study
(Elsevier, 1977-06-20)
The administration of a single convulsant dose or of multiple subconvulsant doses of L-methionine-dl-sulfoximine (MSO) to 18-day old rats results in a significant elevation of the specific activity of cerebral tRNA ...
Preparation of 6‐ 3 H glucocerebroside
(John Wiley & Sons, Ltd., 1977)
Glucocerebroside (1–0‐β‐glucosyl ceramide) can be labeled with 3 H‐borohydride at the 6‐position of the glucose moiety. The 6‐trityl ether of cerebroside is formed first, the remaining hydroxyl groups are acetylated, the ...
Banding pattern and fibrillogenesis of ceratotrichia in shark fins
(Wiley Subscription Services, Inc., A Wiley Company, 1977-11)
Study by light microscopy, scanning electron microscopy and transmission electron microscopy of the distribution, structure and growth of ceratotrichia in the anterodorsal fin of a lemon shark, Negaprion brevirostris , ...
Olfactory and vomeronasal deafferentation of male hamsters: Histological and behavioral analyses
(Elsevier, 1977-05-06)
Deafferentation of the vomeronasal system by cutting the vomeronasal nerves severely impaired mating behavior in 44% of male hamsters over a 1-2 month period of postoperative testing, but the remaining males mated normally ...
Osmoregulation in Blaberus craniifer after parenteral injections of NaCl solutions
(Elsevier, 1977)
1. 1. After injection of NaCl into the abdominal hemocoel of Blaberus craniifer, the osmotic concentration of antennal hemolymph peaked at 1.25hr and returned to pre-injection concentration by 21 hr. The mean plasma clearance ...
Teratogenicity of polybrominated biphenyls in rats
(Elsevier, 1977-08)
The teratogenic potential of a mixture of polybrominated biphenyls (PBB) was investigated. Pregnant Wistar albino rats were given single doses of PBB in seasame oil by gavage on one day of pregnancy, from day 6 through 14 ...
Complexity effects in form detection
(Elsevier, 1977)
This study examines the effect of pattern complexity on the detectability of dotted target patterns presented in dotted visual noise. The effects of complexity on performance in this detection task were shown to be ...
Controlling hypertension: A cost-effective model
(Elsevier, 1977-06)
A model system for controlling hypertension that was developed and tested in three industrial settings and three community settings is described. Data
Developmental patterns of glycolytic enzymes in regenerating skeletal muscle after autogenous free grafting
(Elsevier, 1977-12)
Extensor digitorum longus muscles of rats were removed and injected with a solution of Marcaine plus hyaluronidase. After incubation in Marcaine solution for 10 min, the muscles were grafted into their original beds. The ...
